The P16 connector breakout provides convenient access to all P16 signals through an MDR68 connector and eSATA high-speed connectors. eSATA connectors allow high-speed connections to P16 SERDES-capable signals.

The adapter is completely transparent to PCI Express. All signals from the PCI Express host bus are connected directly to the XMC module.

More power to the XMC module may be provided by using the optional power connector to the adapter card. The power connector provides +12V to the adapter and powers an on-card 3.3V, 8A DC-DC module. The power connector is compatible with standard 0.165” pitch 12V PC power connectors.

Conduction cooling using VITA20 standard, as well as an optional fan, provides cooling to the XMC module.

The XMC module mounts securely to the adapter using standoffs and with the end bracket. The bracket mates to standard PMC end brackets and supports an EMI gasket. All connectors from the XMC end bracket are fully accessible.
